Description:

In this present research the design and fabrication of a Lathe’s Dynamometer of two channels for measuring the cutting force and feed force is studied. The dynamometer of two cantilever was designed by drawing in a CAD Software and simulated by finite element model with the condition that not exceed the yield stress and deflection is minimal and this deflection within the parameters of forces that we want to measure . The dynamometer uses two dial indicators with high sensitivity to measure displacement. In order to relate Force and displacement is necessary to establish a sensitivity curve that transform displacements in forces. The device was applied to the analysis of cutting forces and feed forces in orthogonal cutting for turning AISI SAE 1020 steel, this material is very common and we have a lot of data and references.
